Galaxy S6 & edge owners beware, Samsung's Clear View case scratches screens
The original thread at XDA, where users post photos and voice their complaints, is already 6 pages thick with content, which means the issue is serious. If you own the Clear View case, there's a high probability of it scratching your Galaxy S6 or edge's display eventually, unless you applied a screen protector. If you don't, you should probably hold off on buying the $60 case and opt for a different product. Meanwhile, Samsung is yet to make an official statement on the issue. Affected users have been turning to customer support in their respective countries, with various degrees of success.
